[FEAT] Add an example of a project using Rolldown

[tbouffard]

https://github.com/rolldown-rs/rolldown: rust based bundler that targets to be compatible with the Rollup ecosystem.

Note that on 2023-03-13: Rolldown is in alpha and is not production ready.

• Latest release 2021-10-15 https://github.com/rolldown-rs/rolldown/releases/tag/%40rolldown%2Fcore%400.1.2
• 2023-03-11 roadmap 0.2 announce: fix: make sure namespace name is valid identifier rolldown/rolldown#107 that should bring support to rollup commonjs that we need at least to bundle mxGraph.
• But this will ensure that projects using Rolldown can integrate bpmn-visualization seamlessly, like for [FEAT] Add an example of a project using Turbopack #423 and [FEAT] Add an example of a project using Rspack #478.

Note: bundler found in the Rspack readme (credits paragraph).

Contribution guidelines

• first, post a comment to mention you are interested in contributing, then you will be assigned to the issue
• we prefer TypeScript projects
• store it in a sub-folder of the projects directory
• choose use case
  • It can be a basic integration that simply displays the diagram, or use an API as we do in the "projects" showing how to integrate bpmn-visualization with build tools and bundlers.
  • It is perfectly valid to provide a contribution using the framework starter kit.
  • It can include dedicated use cases, as Angular or Vue integrations do.

In any case, please communicate with the maintainers of this repository (with this issue) about what you want to implement (especially the use case) to make sure we're aligned on this.
This will speed up the review and final integration into the examples.
